Bump Rubber .500in Thick 2in OD x .625in ID Black

The bump rubber .500in thick 2in OD x .625in ID black puck from RE Suspension is a precision suspension component engineered for vehicles running lowered setups or aggressive ride heights. This bump stop serves as a mechanical travel limit, preventing suspension components from bottoming out under extreme compression—a critical safety feature for trucks, performance cars, and modified vehicles where spring rates and ride geometry have been altered from factory specifications. Whether you're building a daily driver on coilovers or a competition vehicle, this elastomeric spacer protects your suspension from catastrophic metal-to-metal contact.

Manufactured as a 5153 series puck with 75-durometer extra-hard foam construction, this bump rubber delivers consistent progressive resistance across repeated compression cycles without permanent deformation. The 0.5-inch thickness and 2-inch outer diameter are engineered to fit standard suspension mounting points, while the 0.625-inch inner diameter accommodates common suspension rod diameters. The black foam material provides excellent damping characteristics—absorbing energy and dissipating heat during suspension articulation—while the extra-hard durometer rating ensures longevity under sustained track use or heavy-duty off-road applications where suspension sees repeated max-travel events.

This bump stop is ideal for mechanics and enthusiasts upgrading coilover kits, custom suspension builds, or rebuilding worn OEM bump stops that have lost elasticity. Installation is straightforward—simply slide the puck onto the suspension rod above the spring perch or into the designated mounting pocket. Its compact 0.04-pound weight adds negligible unsprung mass, making it suitable for performance-oriented applications where every ounce matters. Verify inner diameter compatibility with your suspension rod before ordering to ensure proper fit and performance across your entire suspension travel range.
